When youre talking about 'smoking 1 time', about how much did you smoke during that "1 time"? (Was it 1 hit? Did you smoke up a whole oz sack? etc)

Anyway, there is no telling. Each persons body is different and there are too many variables to take into consideration. Only testing yourself with a THC test kit (using the first urination of the day) can give you the answer to your question.
